Did not work; no support
Rating: 1/5
Installed the product according to the directions on my Dell Inspiron 5100 running XP Pro. It never recognized the HP OfficeJet Printer. Uninstalled; reinstalled - no luck. Contacted customer support twice. No response.
Poor offering for $50.00

I bought this because I needed a serial & parallel port on my laptop. It did not work for my HP printer (I should have checked with HP first!) makes me wonder what their "works with hundreds of printers" ad-line means. The driver installation for windows is not something a novice user would want to deal with when it goes wrong (I had to uninstall/reinstall, and even then it's got to be in perfect sequence or the device won't show up). And for even the slightest power-drain on the USB bus, this device won't deliver -- in all it became nothing more than a lit up chunk of plastic sitting behind my notebook. I've opted to return it for refund. Oh, and I contacted Keyspan about the printer problem, 7 days later and I've heard nothing. That's not tech support in my book.
